Answer:
24 years
Step-by-step explanation:
let Donald's age be x
then Nicole's age would be 1/2 * x = x/2
now, x + x/2 = 72
3x/2 = 72
3x = 72*2
x = 144/3 = 48
Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.
Please help meeeeeeeeee
Step-by-step explanation:
1. 10-(2+3) = 5
2. 2x3 - 10 = -4
3. 3 x (4-2) = 6
4. (3+5) / 4 = 2
5. (5-2) x 3 = 9
6. (9-4) + 5 = 10
Which one of the numbers does not belong in the following series?
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
A-FIVE
B-SEVEN
C-FOURTEEN
D-FORTY-ONE
E-ONE HUNDRED TWENTY-TWO
Answer:
i think 7
Step-by-step explanation:
Option B: SEVEN
The number that goes not belong in the following series is SEVEN
Given :
The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .

Answer:
Area: 312
Perimeter: 75
Step-by-step explanation:
Area is l·w
20·16=320
two corners aren't filled
320-9-9=318
Add all the sides for perimeter
17+3+3+13+20+13+3+3=75
Answer:
281 m squared
Step-by-step explanation:
What we can first do is find the top length so we can do
17+3+3=23
then we can multiply it by the side length to get the whole rectangle
23*13=299
and we know each of the little areas is 9, and there are two so
9+9=18
and we can subtract that from the whole rectangle
299-18=281

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?
Answer:
$3.50
Step-by-step explanation:
to find the range you take the highest number and the lowest number and subtract them
so with that, let us do just that-
$5.75, $3.75, $3.25, $2.25
$5.75-$2.25
=$3.5
and since we're dealing with money we must add a '0' to the end of the decimal- $3.50
good luck :)
i hope this helps

Find the area of the shaded region.
help pls
Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm

Aimee has 2 sisters in her family. She thinks the probability of a family having 3 children who are all girls is ¼ because there can be 0 girls, 1 girl, 2 girls or 3 girls.
Aimee designs a simulation to test her prediction. She flips a coin 3 times in a row and records the results. She uses heads to represent a girl and tails to represent a boy. After 10 trials of this simulation, Aimee gets the following results.
1 2 3 4 5 6 7 8 9 10
BBB GBB GGG GGB BBG GGB BGG BGB BBG GBB
Does ¼ seem like a reasonable probability of having 3 girls? Use a tree diagram to model and support your thinking.
Estimate the probability of having 3 girls using the results from Aimee’s simulation.

You choose between red or yellow wallpaper, and orange, red, green, blue, or purple carpet. Use the fundamental counting principle to find the total number of possible outcomes when you select one color of wallpaper and one color of carpet. *
7
5
10
12
Answer:
C. 10
Step-by-step explanation:
There are 5 choices of carpet, and 2 choices of wallpaper. This means that there are only 10 possible outcomes.
The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,
⇒ 10
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
You choose between red or yellow wallpaper,
And, orange, red, green, blue, or purple carpet.
Since, There are 2 wallpapers.
And, There are 5 carpets.
Hence, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,
⇒ ²C₁ × ⁵C₁
⇒ 2 × 5
⇒ 10
Thus, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is, 10

Answer:
Part A: 56
Part B: 43.9
Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean
Step-by-step explanation:
Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.
Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.
Part C: explanation in answer.

I am using the graphing calculator my school uses for exams. But here is the step by step anyway
5x + 36 = 2x + 96
(5x - 2x) + 36 = (2x - 2x) + 96
3x + 36 = 96
3x + (36 - 36) = (96 - 36)
3x = 60
(3x ÷ 3) = (60 ÷ 3)
x = 20
x represents weeks

Suppose 288 electricians took a certification test that is worth 140 points. The five-number summary for the scores is shown here.
min. value = 68
Q1 = 110
median = 125
Q3 = 130
max. value = 138
About how many electricians had a score of 110 or less? A: 72 B: 130 C: 144 D: 216
Answer:
72
Step-by-step explanation:
For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:
0.25 * 288 = 72.
Gabe goes to the mall. If b is the number of items he bought, the expression 17.91b+27 gives the amount he spent in dollars at one store. Then he spent 22 dollars at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought 4 items.
Answer:
(17.91b+27)+22 is the expression
and the estimate will be 121 because u will do 18 times 4=72 and the add 22 and then 27.
